How many nuclei does an Entamoeba cyst have?
Mature cysts typically have 8 nuclei but may have as many as 16 or more. Entamoeba coli is the only Entamoeba species found in humans that has more than four nuclei in the cyst stage. The nuclei may be seen in unstained as well as stained specimens.
Entamoeba coli cyst with more than four nuclei. The presence of E.coli is not cause in and of itself to seek treatment as it is considered harmless. However, when a person becomes infected with this benign entamoeba, other pathogenic organisms may have been introduced as well, and these other pathogens might cause infection or illness.
Aug 23, 2023 · On initial microscopy, the cyst of Entamoeba coli typically has eight nuclei, while Entamoeba histolytica typically has four. The peripheral chromatin is coarse and irregularly clumped for Entamoeba coli and fine, evenly distributed for Entamoeba histolytica.

Trophozoites of E. coli measure 15–50 μm and have a single nucleus with irregular peripheral chromatin and a usually eccentric karyosome. The cytoplasm is often described as “dirty” and may contain vacuoles and ingested food particles, including bacteria, yeast, and even other intestinal protozoa.
Apr 18, 2021 · Entamoeba trophozoites have a single nucleus, whereas mature cysts are tetranucleate [36,37]. As E. histolytica undergoes stage conversion within the colon, the nuclei begin dividing. Trophozoites that begin encysting during the G1/G0 phase of the cell cycle form cysts at a 1:1 ratio in which one trophozoite produces one cyst.
